tapi

[wangxbing]

Please:

I am learning VC++6.0.
I can not resolve the following problem:

error LNK2001: unresolved external symbol _CLSID_TAPI
error LNK2001: unresolved external symbol _IID_ITTAPI
Debug/tele3.exe : fatal error LNK1120: 2 unresolved externals


How can I do?

My source:
...
#include <tapi3.h>
...
ITTAPI * pTapi;
CoCreateInstance(CLSID_TAPI,NULL,CLSCTX_INPROC_SERVER,
IID_ITTAPI,
(LPVOID *)&pTapi
);
...
